Composer kemu (KEMU VOXX) first uploaded 六兆年と一夜物語 to niconico douga on April 13, 2012, featuring the Vocaloid IA. The song rocketed past the site's 殿堂入り (hall of fame) threshold of 100,000 views within 48 hours and crossed one million views by early July of the same year, establishing itself as one of kemu's landmark Vocaloid works. The title, translating roughly to "Six Trillion Years and Overnight Story", frames the track's cinematic scope: a driving rock arrangement with dramatic, storybook vocal delivery that resonated deeply with the niconico audience and has kept the song a staple of kemu's discography. In maimai, 六兆年と一夜物語 arrived during the ORANGE PLUS update as part of a promotional tie-in with Sega's CHUNITHM. For the first few months, the song was only playable in maimai if players had also played it in CHUNITHM, a cross-arcade unlock system that encouraged engagement across both rhythm game cabinets. General availability followed on October 29, 2015. The song later received DX-format charts on July 11, 2019, alongside maimai's transition to the DX hardware line, ensuring its continued presence through multiple game editions. The two MASTER charts, Standard by Jack and DX by うさぎランドリー, both sit at level 13+, reflecting the relentless BPM 186 pace and dense patterning. The DX Expert chart by 華火職人 stands out for its heavy use of Touch notes, integrating the DX cabinet's touch-sensor mechanics at a relatively approachable level 9 difficulty. Across both chart sets, 六兆年と一夜物語 has undergone several level adjustments through maimai's version history, a testament to its longevity and continued relevance as a high-speed Vocaloid boss track.
